The Three Worlds of God, Human and Demon each have different rules.
These rules are called the Heaven and Earth Laws.
No one knows who set down the Heaven and Earth Laws, but even gods must obey them.
One of the Heaven and Earth Laws of the Divine Realm is that they cannot interfere in the affairs of other realms.
Back then, Xi Jiuye's father Xi Sanqian was killed by Ye Beiming and Mingri precisely because he violated this law.
But Xi Sanqian had once been the trusted aide of the Feng Gu Divine Emperor, so because of this, the Feng Gu Divine Emperor always held a grudge against Ye Beiming and Mingri, and even schemed to harm the Yun Sheng couple back then.
Fortunately, the Huo Yan Emperor, one of the Four Divine Emperors, stepped forward together with the other two Divine Emperors, and only then were the Yun Sheng couple preserved.
